DEMAND PERFECTION Hitachi has developed the ZX135US-6 with a sliding arm mechanism specifically for deep excavation projects in confined spaces. It can dig deeper and has a significantly smaller footprint than a 30-tonne standard model. This makes it the perfect machine for urban and road construction projects, and particularly the installation of pipes for utilities. High quality Only the best design elements and materials. Lifetime reliability Reliable components help to prevent oil leaks. Ultimate durability Robust sliding structure resists wear. 2
ZX135US 6 Compact design Digs deeper than larger models in smaller workspaces. Optimum performance Remote monitoring with Global e-service online application. User-friendly Safety comes first with handrails and a reinforced safety platform. Low emissions SCR system reduces NOx from exhaust gas. Low fuel consumption 7% fuel saving in PWR mode (5% in ECO mode). Easy maintenance Sliding plates are easy to replace. Excellent efficiency HIOS IV reduces total hydraulic loss. Superior control Exclusive hydraulic circuit enables smooth operation. 3
ZX135US 6 POWERFUL PERFORMANCE Hitachi has utilised its excavator manufacturing expertise to address the need for powerful machines capable of working in confined spaces. The ZX135US-6 with sliding arm has been developed in-house as a compact alternative to larger models, capable of digging further and with a significantly smaller footprint. It will complete excavation tasks quickly and efficiently, enabling projects to be executed safely and on schedule. Powerful versatility The upper arm features a built-in sliding cylinder with a 2,000mm stroke. With a maximum digging depth of 7,790mm, it has an extended working range compared with similar-sized machines and is ideal for river maintenance, pipeline constructions and building mine shafts. Superior control The robust sliding structure supports the arm movement to prevent jolting and ensure a smooth operation. The controlled combined operation of boom and arm, and exclusive Hitachi hydraulic circuit, is ideal for slope finishing. Easy maintenance Lubrication points on the sliding structure increase reliability and contribute to easy maintenance. The nylon sliding plates can be replaced quickly and conveniently. The sliding arm extends the working range of the ZX135US-6. 4
Short swing radius ensures the ZX135US-6 fits perfectly in small spaces. Combined operation of boom and arm enables smooth slope finishing. 5

LIFTING CAPACITIES Notes: 1. Ratings are based on ISO 10567. 2. Lifting capacity does not exceed 75% of tipping load with the machine on firm, level ground or 87% full hydraulic capacity. 3. The load point is the center-line of the bucket pivot mounting pin on the arm. 4. *Indicates load limited by hydraulic capacity. 5. 0 m = Ground. 6. Never attempt to carry out lifting operation with extending the sliding arm. For lifting capacities, subtract bucket and quick hitch weight from lifting capacities.
